“Age is just a number” might work for chasing dreams — but not when it comes to shoveling snow.

Research shows that for men over a certain age, heavy snowfall can significantly raise the risk of heart attacks and sudden cardiac death. One large Canadian study found that after major snowstorms, heart attacks in men rose by about 16%, with deaths increasing even more. Experts say it’s not just the snow — it’s the way we clear it.

Wet snow is extremely heavy. Studies show the average shovel load can weigh around 16 pounds. At a steady pace, that can add up to lifting nearly 2,000 pounds in 10 minutes — while your heart rate climbs close to maximum levels, sometimes even higher than during a treadmill stress test.

Cold weather makes things worse. Breathing in cold air causes blood vessels to constrict, raising blood pressure and making it harder for blood to reach the heart. Combine that with sudden heavy exertion and you have a serious strain on the cardiovascular system.

Why Shoveling Is So Hard on the Heart

Shoveling snow stresses the body in unique ways:

• It’s static exertion — standing still while lifting heavy loads

• It relies heavily on arm work, which is tougher on the heart than leg movement

• People often hold their breath while lifting, spiking blood pressure

• Limited leg movement can cause blood to pool instead of circulating well

• Cold temperatures narrow arteries, reducing blood flow to the heart

What Age Has to Do With It

Younger adults typically haven’t developed significant heart disease yet. But after about 45–50 years old, many people — even those without symptoms — may have some level of hidden coronary artery disease. Risk increases further if you’re sedentary, smoke, or have diabetes, high cholesterol, or high blood pressure.

Even people who feel fine may be unaware of underlying heart issues. Sometimes, experts say, a heart attack during heavy exertion is the first warning sign.

Safer Ways to Clear Snow

Doctors recommend reducing strain whenever possible:

• Hire help if you’re older or have heart risk factors

• Push snow instead of lifting it

• Dress warmly in layers, especially covering your face, hands, and head

• Avoid big meals, alcohol, or smoking before shoveling

• Work in short intervals and take frequent breaks

• Use a snow blower instead of a shovel when possible

Don’t Ignore Symptoms

Stop immediately if you feel chest pain, shortness of breath, discomfort in the arms, neck, jaw, or shoulders, dizziness, or nausea. If symptoms don’t go away quickly, call 911.
